on snow, disrupted travel and isolation on white


along with thousands of other travelers in Europe we didn't travel anywhere. So we are probably not really qualify to be called travelers at all.

We were supposed to fly to Fuerteventura on Sunday morning (very early morning, so favoured by cheap airlines). We didn't, because the evening before a lot (I mean A LOT) or snow fallen and settled on the ground. It was very respectable amount of snow for single snowfall, even if I apply russian standard to it.

Anyways. On Sunday, while the snow was still fresh, I went out with my camera, and got pictures of a few trees, isolated on white background, small twigs and all. And just wanted to stress again how easy it is if the original lighting is right - be it natural milky-white sky or studio setup.

I am pretty sure I first saw a variant of this technique described by Laurin Rinder on shutterstock forum. He wrote something like "just call up Levels dialogue in photoshop, take a white pipette and click on background". And it works perfectly well if background was white and uniformly lit.

A goodish while ago wrote up a slight variation on this here - that works nicely even is there are dirty patches on the background.

I continue to use more or less the same technique now when conditions are right. I call up Levels dialogue, and start dragging the white point (upwards arrow on the right of the diagram), while holding Alt key (for PC) visually controlling the results. Sometimes it works just like that, sometimes I need to play with a few layers, but it works very nicely. Hope it helps if someone is still struggling with isolation.
